Connecting to SQL Server from Android and iOS in Direct Mode Using SDAC

Using SDAC in Direct Mode for access to SQL Server from iOS and Android platforms doesn’t significantly differ from the one on Mac OS X or Windows platforms. Let’s see how this works in a sample below for RAD Studio XE7.Note: those, who have already read our previous article Connecting to SQL Server on Mac OS X in Direct Mode Using SDAC can skip the description of creating a new project and move on to the Project configuration for Android and iOS platforms step.Design-timeLet’s create a new Android / iOS application, that will work with SQL Server. For this, in the File|New menu select Multi-Device Application – Delphi.

In the appeared dialog select Blank Application.

Place the TMSConnection component onto the form, which will be named as MSConnection1. Set up the MSConnection1 component by setting the Options.Provider ProviderName property to prDirect. Open MSConnection1 editor and fill in the required properties: Server, Port, Authentication (the SQL Server value), Username, Password and Database.

MSConnection1 settings for Direct Mode have been done.

Now we just have to write event handlers for the Connect and Disconnect buttons:procedure TMainForm.ConnectClick(Sender: TObject);begin MSConnection1.Connect; MSQuery1.Open;end; procedure TMainForm.DisconnectClick(Sender: TObject);begin MSQuery1.Close; MSConnection1.Disconnect;end;Setting up Direct Mode for AndroidWhen developing Android applications working with SQL Server in Direct Mode, SDAC doesn’t require any additional settings for deployment and execution. For my sample, I have just selected Target Platform – Android and a device.

Application execution in Direct Mode on AndroidIn RAD Studio press F9 and in a few seconds get the application running on Android, that works with SQL Server in Direct Mode with the help of SDAC.

Setting up Direct Mode for iOSWhen developing iOS applications working with SQL Server in Direct Mode, SDAC doesn’t require any additional settings for deployment and execution. For my sample, I have just selected Target Platform – iOS and a device.

In such a way, we have demonstrated how easy to use SDAC functionality – Direct Mode for SQL Server when developing applications for Android and iOS. The source code of this demo can be found in the SDAC Demo folder on your PC.
